5 More Ways to Destroy an Arduino

This week’s episode builds on the previous episode by highlighting five more ways you can damage/destroy an Arduino.

We will cover:

Mistake #6: Applying >3.3V to the 3.3V Connector Pin

Mistake #7: Shorting Vin to GND (when powering with the DC power jack)

Mistake #8: Applying 5V External Power with a Load on Vin

Mistake #9: Applying >13V to the Reset Pin

Mistake #10: Exceeding the Total Microcontroller Current of 200mA

We also learn more about an Arduino UNO derivate designed to protect against each potential mishap.

Rugged Circuits: How Not To Destroy an Arduino

All of the material in this video is based on a really great article written by a company named Rugged Circuits.

Rugged Circuits is US based. They manufacture and sell an Arduino Uno derivative board called the “Ruggeduino”.

The Ruggeduino protects against every form of destruction we talk about in this week’s video.


It’s kind of like the superhero of Arduino derivative boards – it’s pretty much invincible. It prevents simple mistakes from destroying it.

Here is a link to the article (It’s a great read and I highly recommend checking it out):
